How does a Strehler Papillon actually work?

We got so mesmerized by the weird reading of time that I forgot to ask a simple question:  How does it work?

Forget about the hour display at the top and the minutes display at the bottom with fixed papillon bridges and rotating sub-dials.

The technical blurb reads:

"Spring barrels normally turn too slowly for the display of minutes and too fast for the hours. But in the Papillon the timing works differently. Its spring barrels are not firmly tied into the sequence of the movement. As a result the time display can be adjusted by means of the hand setting. In addition, two giant gear wheels with 192 and 175 teeth remove the need for a third wheel. This reduction in the number of wheels and the double spring barrel arrangement result in energy savings which extend the life of the watch enormously."

But what does that mean actually?

If there is only 1 escapement, no 3rd wheel and 2 rotating display discs  --   how is it all connected for time-keeping? How does ONE escapement output link to TWO display dials without a linking 3rd wheel?

Answers understandable by mere mortals required......
